Let's look back at 2025, it was year full of difficulties but also of small victories. Bending of the anode grid on our in-house press break [...]

The development of the F nixie tube has proven to be beyond our current resources, both economically and in terms of project scale. As a result, I’ve decided [...]

The progress on the F tube development in the past weeks was small, but considering the limited time, it is still a success. Sealing machine is waiting for [...]

Sides of the stem are heated properly, but what about the center? This is much more difficult.. I need to find a way to heat the center without [...]

I am still struggling with development of the stem press, but some progress was made - the ejection mechanism that pushes the glass out of the mold is [...]

The molds were finished; great time to put in some glass and try pressing stems. There is progress, but the journey to a fully functional stem will be [...]

The molds are finished, we can do another test molding the glass soon! […]

The pins for glass stems arrived, we are planning another machine - another piece of the F tube puzzle! https://www.youtube.com/watch?v=etDg_L218rQ

I machined the holders for the glass forming molds, a few more parts, and we can melt some glass! https://www.youtube.com/watch?v=CNNqe-lsv6E

The new mold design is ready, the glass lathe seems to be aligned well to use it.. Now we need to machine it! https://www.youtube.com/watch?v=IIyQdCU-Ww0

Another version of a mold for manufacturing stems is in development. Meanwhile, I am trying the process of cutting wires to pins - this will be needed once [...]

We need to develop a stem press machine for the new F nixie tube. A complex task that needs to be done step by step. In this video, [...]

We are starting a new project, development of a new nixie tube called F. Stay tuned for more info ;-) https://www.youtube.com/watch?v=KI3Te3UjatY

The installation made with the large H nixie tubes is getting tempo.. https://www.youtube.com/watch?v=tTh-lvdNO_0

The previous batch of H tubes is finished, we experiment with making a flange on glass cylinder and test a new jig for making the glass relays. https://www.youtube.com/watch?v=3xi_3JOswNE

The small batch of H tubes with reinforced digits is ready to be finished - put on aging. It doesn't go smooth, as usual.. https://www.youtube.com/watch?v=LaSmXzlmxms

A new batch of digits arrived, so we can continue in prototyping the H tube. We can't forget about the R tube production and the Puri clocks that [...]

We have parts for 10 more H tubes, I am now trying to get them to finished tubes so we can look at the problems and make design [...]

The new space for the development of our nixie tubes is already serving its purpose, so I am able to continue on the H tube project. The problem [...]

Since I started manufacturing and selling nixie tubes and clocks, our customers from the USA formed the single biggest market for us. [...]
